What happened
During a descent toward Belgrade-Zemun Airport, the crew of a three-engine aircraft named 'Johannes Höroldt' encountered marginal weather conditions characterized by low clouds while passing over Novi Sad. The aircraft, which was operating in the vicinity of Bukovac, impacted the north slope of Mt Fruška Gora. The crash site was located on the mountain's northern face, at an elevation of 380 metres. Debris was recovered less than 30 metres below the summit. All 17 occupants on board were killed in the accident.
Findings
The official investigation concluded that the accident resulted from controlled flight into terrain. A critical contributing factor was identified as erroneous weather information provided to the crew. The data transmitted indicated a cloud base of 600 metres, but the actual cloud base at the time of the impact was significantly lower than this reported figure, creating a hazardous situation for the descending aircraft.
